This section for single precision can exist all on its own. It can be used regardless of the 3 multi-precision math library options as long as WOLFSSL_SP_MATH is not defined.

/* Use only single precision (SP) math and algorithms.
* SP math is written to accelerate specific/common key
* sizes and curves. This adds code from sp_c32.c, or one of the specific
* assembly implementations like sp_cortexm.c. This code is faster than the
* multi-precision support because it's optimized for the key/curve.
* The SP math can be used together with any multi-precision math library
* if WOLFSSL_SP_MATH is removed. If only standard keys/curves are being
* used the multi-precision math is not required.
